I have just recently upgraded firefox to the newest version (3.0.1) and i am running on windows vista business edition. When i open the downloads window, it isn't like before with the remove and open buttons. Help please!!! I don't know how to open a downloaded file after it finished downloading.

go to the folder that u saved it to

Double click on an item to open it. Right click on an item to get more options. Select an item and hit the Delete key above the arrow keys to delete an item.
